Does this calculator include origination or late fees?

No. It focuses on the core principal-and-interest math. If an origination fee is financed into the loan, add it to the loan amount. Late fees and penalties are not modeled at all.

Can I use this for debt consolidation planning?

Yes. Add up the balances you want to consolidate and enter that as the loan amount, along with the APR and term on the consolidation loan, then compare the payment and total interest to what you pay today.

Is this the same as a credit card payoff calculator?

Not exactly. Credit cards are revolving debt with variable payments and often changing rates. This tool assumes a fixed-rate installment loan with a level payment schedule.

Will lenders use exactly the same numbers?

Most lenders use the same amortization math, but small differences can come from rounding, timing of the first payment, and how they handle fees. Treat this as a close estimate and verify final terms on any disclosure documents you receive.

Personal Loan Calculator

Estimate your monthly payment, total interest, and total cost for any fixed-rate personal loan using loan amount, APR, and term.

Results

Estimated monthly payment: $484 USD
Total interest paid: $2,422 USD
Total paid over life of loan: $17,422 USD

Overview

Personal loans are a common way to consolidate high-interest credit cards, cover an unexpected expense, or finance a big purchase without putting it on plastic. The key question is almost always the same: what will my monthly payment be, and how much extra interest will I pay over time? This personal loan calculator turns loan amount, APR, and term into clear monthly payment, total interest, and total cost figures so you can sanity-check offers before you sign anything.

How to use this calculator

Enter the personal loan amount you are considering. Include any origination fee that will be financed into the balance if your lender rolls it into the loan instead of charging it upfront.
Enter the APR quoted by the lender. If you are comparing multiple offers, plug in each APR one at a time to see how much the rate changes the payment and total interest.
Enter the term in years (for example, 3, 4, or 5 years). Longer terms reduce the payment but increase total interest.
Review the estimated monthly payment, total interest, and total amount paid over the full term.
Adjust amount, APR, and term until you find a combination that fits both your monthly budget and your tolerance for total interest cost.

Inputs explained

Loan amount: The principal you plan to borrow. If your lender finances an origination fee or other charges into the loan instead of taking them out of the proceeds, include those amounts so the payment estimate reflects the full financed balance.
Interest rate (APR): The annual percentage rate on the loan, expressed as a percentage. APR reflects the yearly cost of borrowing, including finance charges that are folded into the rate. The calculator converts this to a monthly rate for the amortization math.
Term length: How long you have to repay the loan, in years. Personal loans most commonly run 2–7 years. Shorter terms increase the payment but reduce the total interest paid; longer terms do the opposite.

Outputs explained

Estimated monthly payment: The fixed payment you would make every month for the full term, assuming the APR and term do not change and you follow the standard schedule.
Total interest paid: The sum of all interest charges over the life of the loan. This is the extra cost of borrowing on top of the amount you originally received.
Total paid over life of loan: The total of all payments you make (principal plus interest) from day one until the loan is paid off. It equals loan amount plus total interest.

How it works

Most personal loans are fixed-rate installment loans. You borrow a lump sum and repay it with equal monthly payments over a set term (for example, 3 or 5 years). Each payment includes both interest and principal.

The calculator starts by converting your annual percentage rate (APR) into a monthly rate by dividing by 12 and turning the percent into a decimal.

It then converts your term in years into the total number of monthly payments (years × 12).

When APR is greater than zero, it applies the standard amortization formula to solve for the level monthly payment that pays off the loan exactly at the end of the term.

If you enter a 0% APR—for example, a promotional or family loan—the calculator simply divides the principal evenly across the total number of months, since there is no interest cost.

Once the monthly payment is known, the total paid is just payment × number of months, and total interest is total paid minus the original loan amount.

Formula

If APR > 0:
  r = APR ÷ 100 ÷ 12  (monthly rate)
  n = TermYears × 12
  Payment = P × [r(1 + r)^n] ÷ [(1 + r)^n − 1]
If APR = 0:
  Payment = P ÷ n
Where P is the loan amount and n is the total number of monthly payments.
Total paid = Payment × n
Total interest = Total paid − P

When to use it

Comparing personal loan offers from banks, credit unions, and online lenders before you apply.
Checking how consolidating several credit cards into a single fixed-rate loan would change your monthly payment and total interest.
Seeing how much interest you save by choosing a shorter term or qualifying for a lower APR.
Testing whether a potential payment fits comfortably within your budget before you accept an offer.
Evaluating whether a 0% or very low APR promotion is truly interest-free or just front-loaded with fees.

Tips & cautions

Look at total interest, not just the monthly payment. A much lower payment with a very long term can quietly increase the total cost of the loan.
If you are consolidating debt, compare the total interest on the personal loan to the interest you would otherwise pay on your existing cards or loans over the same timeframe.
Check whether the lender charges an origination fee and whether it is deducted from the loan proceeds or financed into the loan balance.
If you expect to make extra principal payments, use this calculator for a baseline payment, then pair it with an amortization or payoff-with-extra-payments tool to see how prepayments change your timeline.
Run scenarios with slightly higher rates or shorter terms to stress-test your budget before committing.
Assumes a fixed-rate, fully amortizing personal loan with equal monthly payments and no balloon payment at the end.
Does not include origination fees, late fees, or prepayment penalties unless you manually bake financed fees into the loan amount.
Does not model changing interest rates, variable-rate loans, or lines of credit where your balance can move up and down over time.
Does not calculate the impact of extra principal payments; it shows the baseline schedule only.
Does not provide credit advice or approval odds; it assumes you can qualify for the APR and term you enter.

Worked examples

$15,000 personal loan at 10% APR for 3 years

LoanAmount P = $15,000; APR = 10%; TermYears = 3 → n = 36 payments.
Monthly rate r = 0.10 ÷ 12 ≈ 0.008333.
Payment ≈ P × [r(1 + r)^n] ÷ [(1 + r)^n − 1] ≈ $484 per month.
Total paid ≈ $484 × 36 ≈ $17,424; total interest ≈ $2,424.

$8,000 loan at 7.5% APR for 4 years

P = $8,000; APR = 7.5%; TermYears = 4 → n = 48.
Monthly rate r ≈ 0.075 ÷ 12 ≈ 0.00625.
Monthly payment comes out around the mid-$190s, with total interest of roughly $1,300 over the term.

0% APR family loan over 2 years

P = $5,000; APR = 0%; TermYears = 2 → n = 24.
Because APR is 0, Payment = P ÷ n = 5,000 ÷ 24 ≈ $208.33.
Total paid is $5,000 and total interest is $0—simple cost sharing with no interest.

Deep dive

Use this personal loan calculator to estimate monthly payments, total interest, and total cost before you commit to a fixed-rate personal loan.
